Description

Technical Field

[0001] The utility model relates to the technical field of tunnel oven equipment, in particular to a baking device used in a tunnel oven for baking products. Background Art

[0002] Food processing tunnel ovens are tunnel-type mechanical equipment that bake food through heat conduction, convection, and radiation. A continuously operating conveyor system operates within the tunnel. During baking, the food moves relative to the conveyor chain, steel belt, or mesh belt, and the electric heating element or direct-fired burner, achieving uniform baking and conveying. Tunnel ovens are generally categorized by heat source: electric, gas, or natural gas.

[0003] The inventors discovered that current electric tunnel ovens primarily rely on electric heating tubes to heat food. However, there's a certain distance between the food being transported and the tubes. Therefore, the farther the food is from the tubes, the lower its temperature becomes, resulting in insufficient heat utilization. Furthermore, the tunnel's inlets and outlets are typically open, and food dust or dirt generated by operations within the workshop can enter the oven, potentially leading to the risk of explosions after the oven jams. Therefore, those skilled in the art have proposed a baking device for a tunnel oven for baked products. Utility Model Content
